Application November 10, 1949, Serial No. 126,483

This invention relates to a device for electrically splicing or connecting the ends of two insulated covered wires, and an object of the invention is to provide a device for this purpose which is simple in construction and by means of Vwhich two ends of insulated wires can be quickly and eiectively connected or spliced electrically.

In order to give an understanding of my invention I have illustrated a selected embodiment in the accompanying drawings, in which,

Fig. 1 is a longitudinal sectional view of a device embodying my invention;

Fig. 2 is a plan view;

Fig. 3 is a section on the line 3-3 Fig. 1;

Fig. 4 is a section on the line 4-4 Fig. 1.

The device herein illustrated comprises a sleeve member I of insulating material which is provided at each end with a wire-receiving recess 2, said recesses extending longitudinally of ythe sleeve and each being of a size to receive the end 3 of an insulated covered wire. The two recesses 2 are separated by the partition portion 4 of the sleeve and the inner ends of the recesses are thus spaced from each other and entirely closed to each other by the material of the sleeve member.

Each recess 2 is formed with a lateral opening 5 which extends to the exterior of the sleeve.

Pivotally mounted on the sleeve is a contact member B of conducting material, said member being shown as pivotally secured to the sleeve member I at l. The contact member B is formed with two laterally extending contact fingers 8 and 9, each finger preferably having a pointed end.

Thevcontact member is swingable about its pivotal connection 1 from an open inoperative position, shown in dotted lines, to a closed operative position, shown in full lines, and the contact fingers 8 and 9 are so positioned that when the contact member is swung into its closed operative position said fingers 8 and 9 will pass through the openings 5. The contact iingers are of suiiicient length so that when the contact member has been moved into its operative position said fingers penetrate the insulating covering II! of the wires and contact with the wire core II thereof as best seen in Fig. 1. By this means the wire cores of the two insulated wires are electrically connected.

The sleeve I is shown as having a longitudinally extending depression or groove I2 in its upper face in which the contact member 6 is received when it is in its operative position, said contact member at this time being conlned between the side walls I3 of said depression I2.

2 Claims.. (Cl. 173--340i The device may be used for splicing or-el'ectrically connecting the ends of two insulated y covered wires each of Which has a sing-le wire core, or it may be used for electrically connecting the ends of two double wires, that is, a wire structure having two wire cores insulated from each other. For this purpose the recesses 2, which are formed in the sleeve I, have the proper cross sectional shape to receive the end of an insulated wire 3 having two wire cores II, and the device will be provided with two contact members 6 arranged side by side, the depression I2 being of a size to receive both contact members. contact members are insulatedfrom each other by means of a central partition I4 of insulating material, and the sleeve is provided with two pairs of lateral openings 5, one pair being situated on one side of the partition I4 and located over one of the cores I I, and the other being located on the other side of said partition and positioned over the other core II. Pivot 1 is surrounded by insulating sleeve I5.

When the two wire ends are-inserted into tlie recesses 2 and the two contact members are swung into their operative position, one contact member will electrically connect one core I I of one wire end to the corresponding core II of the other wire end, while the other contact member will connect electrically the other two corresponding wire cores. and thereby the wires will be electrically spliced.

I claim:

l. A device for electrically splicing insulated wire comprising a sleeve member of insulating material having a wire-receiving recess extending longitudinally thereof from each end, the inner ends of the recesses being spaced from each other and entirely closed to each other by material of the sleeve member, said sleeve member being formed with an exterior longitudinally extending groove and having two openings, one of which connects said groove with the inner end portion of one recess and the other of which connects said groove with the inner end portion of the other recess, a contact member of conducting material pivotally mounted at one end in said groove and adapted to swing about its pivot between a closed operative position in which it is entirely received in said groove and an open inoperative position, said contact member having two laterally extended pointed contact ngers which are located at different points along its length and which are so positioned that when the contact member is in closed position one iinger extends through one opening into one The two recess and the other iinger extends through the other opening into the other recess, said fingers, when the contact member is in closed position, penetrating through the insulation of insulated wire ends occupying said recesses. 5

2. A device for electrically splicing insulated wire comprising a sleeve member of insulating materialV having a wire-receiving recess extending longitudinally thereof from each end, each recess having a shape to receive the end of an 10 member being adapted to swing between its closed 20 operative position in which it is entirely received in its groove and an open inoperative position,

leach, contact member having two laterally exat different points along its length, the contact" fingers of each contact member being so positioned that when the contact member is in closed position one nger extends through one of the corresponding openings into the corresponding recess and the other finger extends through the other opening into its recess, said ngers being of sucient length sovjthat when the contact members are in operative closed position the pointed ends of the fingers penetrate the insulation of insulated wire occupying the recesses.
